Find Max

The buttons “Find Max Core” and “Find Max Mem” allow you to automatically find the maximum clock speeds your card can handle without producing errors.

After clicking one of the Find Max buttons the moving cube will stop. Starting with the current clock speed of either memory or core the clocks will slowly be increased until the first visual error is detected.

After a certain interval (default: 30 seconds) a heatup phase will be started, the cube will move again. While the heatup phase is running (default: 30 seconds) no scanning takes place. This is done to maximize GPU and memory load and increase the card’s temperature. It is possible that your computer will be less responsive during a heat up phase, this is because CPU load is very high as well.
When the heatup phase is finished the cube will stop moving and scanning continues. After a certain time of scanning another heatup phase will be started and so on. All this is configurable under Settings - Artifact Scanning.
If you want to manually start a heatup phase left-click inside the 3D window. Clicking several times makes the heatup phase longer. To shorten a heatup phase right-click inside the 3D window.

As soon as the first visual error is detected, the clocks will stop increasing. Every time another error is detected from now on, clock speed will be decreased by a small step. This is done for unlimited time by default.

You can abort the scanning process any time by clicking “Abort”.

Hiding or minimizing ATITool during Find Max or Scan for Artifacts does not influence the results.

Q: Does ATI Tool prompt, stating the max core found presenting a finite end to the test or will the test run on forever?

A:

Q: After finding the first error the test will decrease the clock speed. Will this run until no more errors are found and prompt showing the recommended clock speed?

A:
